Container having a sonication compartment

Claim 1

A container having a hydration compartment adapted to receive therein a hydrating liquid and a material to be dissolved or dispersed thereinto, the compartment having sidewalls and endwalls and a floor from which an array of finger-like members project vertically upwardly into the compartment, the fingers being spaced from the sidewalls and endwalls with the tips of predetermined ones of the finger-like members being above the tips of others of the members within the compartment, the members being arranged with respect to each other to define a material receiving recess and being relatively spaced apart to define recirculating gaps therebetween such that, in use, the material to be dissolved by the application of ultrasonic energy from a source introduced into the compartment is confined within a relatively high energy zone defined by the recess and hydrating fluid is recirculated through and out of the relatively high energy zone through the gaps between the finger-like members.
